Abstract:
The invention improves the thermal conductivity of the material powder to be fired and also makes it possible to produce an amorphous magnetically soft body within a shortened period of time. The amorphous magnetically soft body is produced by preforming the material powder into a body first, and heating the preformed body without pressing. Stated more specifically, an amorphous magnetically soft body is produced from a material powder comprising a powder of an amorphous magnetically soft alloy, a glass having a softening point lower than the crystallization starting temperature of the alloy and a binding resin, by pressing the material powder in a preforming die to prepare a preformed body by the binding property of the resin, and firing the preformed body without pressing at a temperature higher than the softening point of the glass and lower than the crystallization starting temperature of the alloy to join the particles of the alloy with the glass.
Abstract:
In order to secure stable magnetic properties in a magnet alloy ribbon obtained by a melt rapid cooling method, and obtain excellent magnetic properties and corrosion resistance in a bonded magnet, the area ratio of dimple-like recesses (22) present in the surface (roll surface) of the alloy ribbon in contact with a cooling roll during solidification is defined. As a result, an alloy ribbon for a magnet having stable magnetic properties can be obtained. The use of a powder obtained by grinding such an alloy ribbon enables formation of a bonded magnet having excellent magnetic properties and corrosion resistance.

Abstract:
A magnetic core portion 16, a residual base material portion 42, and a connecting portion 43 are formed by pressing from a base material 40. Notches 18A are formed at a peripheral edge of the magnetic core portion 16, which is bent in the direction of the plate thickness to form a temporary fixing portion 18. When base materials 40 are overlapped to cut the magnetic core portions 16 from the connecting portion 43, the magnetic core portions 16 are pressed in directions toward one another so that the temporary fixing portion 18 is filled between notches 18A in the other magnetic core portion 16, to fix temporarily the other magnetic core portions 16. Since the magnetic core portions 16 are temporarily and simultaneously fixed by pressing in a cutting step normally carried out, the magnetic core portions can be temporarily fixed with ease.

Abstract:
A high efficiency electric motor has a generally polyhedrally shaped bulk amorphous metal magnetic component in which a plurality of layers of amorphous metal strips are laminated together adhesively to form a generally three-dimensional part having the shape of a polyhedron. The bulk amorphous metal magnetic component may include an arcuate surface, and preferably includes two arcuate surfaces that are disposed opposite to each other. The magnetic component is operable at frequencies ranging from about 50 Hz to about 20,000 Hz. When the motor is operated at an excitation frequency “f” to a peak induction level Bmax, the component exhibits a core-loss less than about “L” wherein L is given by the formula L=0.005 f (Bmax)1.5+0.000012 f1.5 (Bmax)1.6, said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively. Performance characteristics of the bulk amorphous metal magnetic component of the present invention are significantly better than those of silicon-steel components operated over the same frequency range.
